With 9/10 episodes done, I think it is safe to say that this won't be getting any better. I had initially come to this show after watching Seven Deadly Sins (the prequel, not the OTHER show called Seven Deadly Sins), and was sorely disappointed by both the episodes actually just being shorts, and the lack of any actual story. In Seven Deadly Sins, the angels were actually made out to possibly be a threat, and the demons were given actually fun characterization, even if it was often cliche. I had expected some sort of continuation of this story.
Instead, what we get is a few impressively bad shorts that aren't actually sexy enough to call hentai, while also lacking in enough plot to be called a story. I have watched actual porn with better plot and characterization than this disappointment of a sequel to an already barely passable show. I even wanted to give it a chance: maybe something interesting will happen once all the angels are introduced. NOPE! Just some skits of tits bouncing around, and bad crotch shots while angels worked out.
Save your time, don't even bother. If you want porn, go watch Hatsu Inu or something. At least the girls in that actually have sex, and you'll have a more interesting plot than whatever was going on in this.
